The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Trends in Canada's bird populations indicator reports population trends of Canada's native bird species from 1970 to 2016. Bird species are categorized into species groups based on their feeding or habitat requirements. Because birds are sensitive to environmental changes, they can be used as an indicator of ecosystem health and the state of biodiversity. Since most bird species are also easily detected and observed, many long-term monitoring programs exist; they provide data on population change dating back to the 1970s (or, in some cases, even earlier). Tracking the status of Canada's birds can help to identify the impacts of these changes, and can also help to set priorities, evaluate management actions and track the recovery of species at risk. Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports. See the supplementary documentation for data sources and details on how those data were collected and how the indicator was calculated.
